Works like Gradient Map in Adobe Photoshop ( http://media.tumblr.com/tumblr_m66m4yiOs91roapsd.jpg) - it's only a six-flag gradient, because the UI gets exponentially longer the more flags there are. No limitations of this one, except one: the flag positions must be in ascending order, otherwise the out-of-order flags will be ignored.
The parameters are numbered, so it's easier to know which parameter is which in the Event Sheet.
Source - specifies the source of the colors to be remaped - 0 is the sprite itself, 1 are the pixels under it.
Intensity - a uniform blend between original colors and remapped colors.
FlagX R, FlagX G, FlagX B - color values for the given flag.
FlagX Position - position of the flag. 0 is far left, 100 is far right. Flag0 is on the far left and Flag5 is on far right. Remember, flags 1 to 4 must be in ascending order otherwise the out-of-order flags will be ignored.
